The amount of AI work to create entire second functioning villagers would be huge. It's not something as simple as adding "CPU controlled units". The foundation of the game's AI just was not designed to do this at all sadly. I would have to completely rewrite half the AI to even get it working on a fundamental level.

i think one thing that could be possible is the trade option. you add a building similar to the old cullus gate you put items in there then you can trade with other gods for items you might want specifically iron and food

This could just be a simpler version of a CPU village. A portal of some sort for inter-dimensional commerce.
